Compiled on September 19th, 2024 by Chase LaSpisa (claspisa@uiowa.edu).

INCLUDED:  

1 Stata data sets: 
 
 FPAr&rdata09232024_final.dta		The final data set for analysis.  
  

2 Stata do files:  
 
  ttw_laspisamitchell_Replicationcode_9.23.24.do 	The file used to run the analysis and create the tables.  
  

1 README file: 
  
  ttw_laspisamitchell_README.txt	Describes the included data and files.  


NOTES:

1. The data set was put together using a number of datasets from different sources. The data set included on this replication page has 	only the relevant variables for replicating the results in the main manuscript as well as the appendices. Please reach out if you 	have any questions regarding the constituent datasets.

2. The models, tables, and figures are estimated and/or created by ttw_laspisamitchell_Replicationcode_9.23.24.do. 

3. The programs are written for Stata version 15 or above (primarily on Stata 17), though they may run in 
	previous versions.

4. Some parts of the results table generation require additional Stata add-on programs, mainly
	the Asdoc and Esstab add-on. To run everything as supplied, please 
	install Asdoc and Esstab using the following command in Stata: ssc install asdoc & ssc install esstab.

5. The final tables included in the main manuscript and analysis were further cleaned using Word functions. This includes deleting spaces 	between rows, adjusting font sizes, or moving variables around such as moving interaction variable terms from the bottom of the 	table to the top of the table. Please look at the whole table as all results should be there, but they may not be in the exact 	same place as the main manuscript and appendices tables.


VARIABLES:

Here are descriptions for all the variables included in the final data set. See the main manuscript for additional details.
